Voters were also asked how they rate Corbett as governor. Three percent said excellent, while more than a third of voters rated him as fair. Another third responded that Corbett was doing a poor job as governor.

Political analyst Dr. Terry Madonna says Corbett has his job cut out for him if he wants to be re-elected.

"We expect to see in the weeks ahead, lots of commercials, many of them negative," said Madonna. "The Corbett campaign has to figure out a way to pull Wolf back so they an make a race out of this."

Voters were also asked if marijuana should be made legal. More than half of the voters said no, but a majority support marijuana use for medicinal purposes.
